15: Reptiles, by drawing their body heat directly from the Sun rather than burning calories to generate it, can survive on ten percent of the nourishment that a mammal of similar size would normally require
A: rather than burning calories to generate it 正确(by drawing body heat from sun rather than burning ….. 即:by v-ing rather than v-ing, 强调两种方式的比较)补充:第2个by 可省,因为两个v-ing都做by 的兵语)
B: rather than the generation of body heat by burning calories (不对称,方式和名词的比较 错!)
C: and not from generating it by burning calories (同理sun 和 ving比较 错)
D: instead of by burning calories for generating it (1.instead of 不如rather than好2.for doing 不如 to do好)
E: instead of body heat generated by burning calories ( 语法ok, 但意思错。并列:by drawing their body heat from sun instead of body heat …..,是两种不同能量(名词)的比较,都做draw的兵语,draw的意思是:吸取…,从外界吸收。所以后者:吸取自己内部产生的能量意思搭背错,即逻辑意思错。)
